Answer:
-13°F is the change in temperature.
Step-by-step explanation:
The change in temperature is,
→ -1 + x = -14
→ x = -14 + 1
→ [ x = -13 ]
Hence, -13°F is the change.

Answer: (y - 2) = - ¹/₄ (x - 10) </h2>
Step-by-step explanation:
When two lines are perpendicular, the product of their slope/gradient = -1. Another way of thinking of this is that they are negative-reciprocal of each other.
Let y = 4x + 6 be [a] & the perpendicular line [b]
since the slope of [a] = 4
then the slope (m) of [b] = - ¹/₄
Since we know the slope of [b], we can use the point-slope form (y - y₁) = m (x - x₁); where (x₁ , y₁) = (10 , 2) & m = - ¹/₄
∴ the equation of the perpendicular line : (y - 2) = - ¹/₄ (x - 10)
Answer:
4 times you divde 20 and 5 and its 4
Step-by-step explanation:
Let the the numbers be x and y:
x+y=-44
thus
y=-44-x
thus the product of the numbers will be:
P(x)=x(-44-x)
P(x)=-44x-x^2
For maximum product P'(x)=0
from P(x),
P'(x)=-44-2x=0
solving for x we get:
-44=2x
thus
x=-22
thus the value of y will be : y=-44--22=-22
hence the answer is:
The numbers that yield maximum product is -22 and -22
